Turning Beer Wastewater into Energy Storage Benefits Breweries, Battery Manufacturers

Beer wastewater can be converted to materials needed to make energy storage cells — a development that researchers say could be a “win-win” for breweries and battery manufacturers.

Wastewater Treatment Captures Carbon Emissions, Produces Energy

A wastewater treatment process developed by engineers at the University of Colorado Boulder mitigates carbon dioxide emissions and actively captures greenhouse gases. The treatment method, known as microbial electrolytic carbon capture (MECC), purifies wastewater by using an electrochemical reaction that absorbs more CO2 than it releases while creating renewable energy … Read more »

New Oil & Gas Wastewater Treatment Process Removes Contaminants, Generates Energy

Engineers at the University of Colorado Boulder have invented a process that can simultaneously remove both salts and organic contaminants from wastewater that comes from oil and gas operations while producing additional energy. The new treatment technology, called microbial capacitive desalination, is similar to a battery in its basic form, but … Read more »

Fracking Chemicals No More Toxic Than Household Substances

Surfactant chemicals analyzed in samples of fracking fluid collected in five states were no more toxic than common household substances such as toothpaste, laxatives and detergent, according to an analysis by researchers at the University of Colorado Boulder. The study, published in the journal Analytical Chemistry, identified surfactants found in … Read more »

Methane Detectors Challenge Finalists Chosen

Five proposals have been chosen as finalists by the Environmental Defense Fund in the Methane Detectors Challenge, an initiative to identify next-generation technologies that will help better monitor and ultimately help reduce methane emissions from oil and natural gas operations. The challenge is being sponsored by EDF and seven partner … Read more »

Study Says Methane Leaks a Concern

An analysis by researchers at the University of Colorado Boulder in the journal Nature Climate Change shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere. The researchers also suggest capturing the methane and using it as a renewable energy source. … Read more »
